It depends on what information you do have. If none, then measure it.
Circumference x (degree/360)
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
The width times pi equals the circumference.
The circumference of a circle is the length of the circle's perimeter.
The total circumference is (arc length) times (360) divided by (the angle degrees)
It depends on what information you do have.
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
I'm assuming that "c" is short for "circumference". The length of an arc is (circumference)*(360/angle). So the length of an arc in a circle with circumference length of 18.84 is 6782.4/angle, where the angle is measured in degrees.
Find the circumference of the whole circle and then multiply that length by 95/360.
find the circumference of the circle and multiply it by the height of the cylinder
